- http://bugs.webkit.org/show_bug.cgi?id=16471 Completions need to be smaller (or not exist at all) SuSpider shows 2.4% speedup. Stop using completions in the execution engine. Instead, the completion type and label target are both stored in the ExecState. * API/JSContextRef.cpp: Removed unneeded include of "completion.h". * bindings/runtime_method.cpp: Removed unused execute function. * bindings/runtime_method.h: Ditto. * kjs/ExecState.h: Added completionType, breakOrContinueTarget, setCompletionType, setNormalCompletion, setBreakCompletion, setContinueCompletion, setReturnValueCompletion, setThrowCompletion, setInterruptedCompletion, m_completionType, and m_breakOrContinueTarget. * kjs/completion.h: Removed constructor and getter for target for break and continue from Completion. This class is now only used for the public API to Interpreter and such. * kjs/date_object.h: Removed unused execute function. * kjs/function.cpp: (KJS::FunctionImp::callAsFunction): Removed some unneeded exception processing. Updated to call the new execute function and to get the completion type from the ExecState. Merged in the execute function, which repeated some of the same logic and was called only from here. (KJS::GlobalFuncImp::callAsFunction): More of the same for eval. * kjs/function.h: Removed execute. * kjs/interpreter.cpp: (KJS::Interpreter::evaluate): Added code to convert the result of execut into a Completion. * kjs/nodes.cpp: (KJS::Node::setErrorCompletion): Renamed from createErrorCompletion. Now sets the completion type in the ExecState. (KJS::Node::rethrowException): Now sets the completion type in the ExecState. (KJS::StatementNode::hitStatement): Now sets the completion type in the ExecState. (KJS::VarStatementNode::execute): Updated to put completion type in the ExecState instead of a Completion object. (KJS::statementListExecute): Ditto. Also changed the for loop to use indices instead of iterators. (KJS::BlockNode::execute): Updated return type. (KJS::EmptyStatementNode::execute): Updated to put completion type in the ExecState instead of a Completion object. (KJS::ExprStatementNode::execute): Ditto. (KJS::IfNode::execute): Ditto. (KJS::DoWhileNode::execute): Ditto. Also streamlined the logic a little to make the normal case a little faster and moved the end outside the loop so that "break" can do a break. (KJS::WhileNode::execute): Ditto. (KJS::ForNode::execute): Ditto. (KJS::ForInNode::execute): Ditto. (KJS::ContinueNode::execute): Updated to put completion type in the ExecState instead of a Completion object. (KJS::BreakNode::execute): Ditto. (KJS::ReturnNode::execute): Ditto. (KJS::WithNode::execute): Ditto. (KJS::CaseClauseNode::executeStatements): Ditto. Also renamed to have execute in its name to reflect the fact that it's a member of the same family of functions. (KJS::CaseBlockNode::executeBlock): Ditto. (KJS::SwitchNode::execute): Ditto. (KJS::LabelNode::execute): Ditto. (KJS::ThrowNode::execute): Ditto. (KJS::TryNode::execute): Ditto. (KJS::ProgramNode::execute): Ditto. (KJS::EvalNode::execute): Ditto. (KJS::FunctionBodyNode::execute): Ditto. (KJS::FuncDeclNode::execute): Ditto. * kjs/nodes.h: Renamed setErrorCompletion to createErrorCompletion, made hitStatement protected, changed return value of execute to a JSValue, renamed evalStatements to executeStatements, and evalBlock to executeBlock. * kjs/number_object.h: Removed unused execute function. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@28887 268f45cc-cd09-0410-ab3c-d52691b4dbfc
